2024年11月3日 · I’m using a W21x44 in the first one and framing the exterior wood trusses into the side. For the 2nd detail, I’m using a W12x26 with a WT12x31 because the beam extends past the step so the beam needs to be lower, but the WT is needed for a portion of the span just to pick up the interior wood trusses on the right side of the detail.

2001年7月25日 · I have a beam that is supporting two bar joists. There is NO kicker from the bar joist bracing the bottom flange against twist, however, it appears that they considered the bar joist as bracing in the weak direction. Is this standard? The axial load on the original design drawing is 147k. The beam used is a W21x44. Its span is 20'. Fy=36ksi.

For your approximate 40' span and 17' tributary width that supports your ceiling and a flat roof, you can use a W21x44 (50 ksi) steel beam. This beam is 6.5" wide, 20.625"deep and weighs 44 pounds per foot of beam. You will need to provide a timber nailer (2x8) bolted to the top flange of the steel beam.

2004年3月5日 · I am reviewing a design that has a beam subjected to 200k-ft max moment and a 32 ft span, the designer has specified a W21x44. When I checked the beam via ASD the compressive flange would have to be braced at least every 4.7-ft to meet the flange criteria.

2006年4月8日 · I have not found the British Sections limiting in their options - unless I am missing something the difference in wt between W21x44(at 65.4 kg/m) and UB533x165x66 kg/m and W24x55 ( 81.8 KG/m) and UB 610x178x82 kg/m is insignificant.
